Question

State any two consequences of siltation in waterways.

Answer 1

Two consequences of siltation in waterways are:

1. Silt accumulation reduces the depth of rivers, lakes, and reservoirs, limiting their ability to hold and convey water, perhaps leading to flooding and inefficient water storage.
2. Siltation can smother aquatic environments, disturb fish spawning grounds, and restrict light penetration, all of which negatively influence aquatic plant and animal health.
